Objective:
To study the technological parameters of the purification process of Depsides in Salvia miltiorrhiza with macroporous resin.
Method:
The adsorptive characteristics and eluting parameters of the process were studied by taking the content of depsides as index.
Result:
85 mL of extractive of depsides (1.25 g x mL(-1)) was purified with a column of macroreticular resin ( Phi30 mm,127 mL) and washed with 4 BV of distilled water, the eluted with 4 BV of 80% ethanol (1% ammonia).
Conclusion:
This process of applying macroporous resin to adsorb and purify depsides in S. miltiorrhiza is feasible.
